Application filed June 22, 1906. Serial No. 322,904.

To all whom it may concern:

Be it known that I, MoReAN D. SADTLER, a citizen of the United States ofAmerica, and a resident of Baltimore city and State of Maryland, haveinvented certain new and useful Improvements in Coin-Testing Machines,of which the following is a specification.

My invention relates to certain new and useful improvements in cointesters adapted to be used in connection with coin controlled machinesof all types.

The object of my invention is to provide a mechanism which will testeach coin dropped into the machine and if it is attempted to operate themachine by what is commonly called a slug, the mechanism will throw outthe slug, though it is of the proper size, diameter, thickness andweight.

My invention tests each coin presented to the machine and unless thecoin is of the proper size, diameter, thickness and made of the propermetal, the tester will not pass the coin in a manner to operate the coinactuating mechanism to which the tester is applied.

In the form of my invention shown, the tester is adapted to test variousdenominations of coins. It is to be understood, however, that the numberof denominations which can be tested may be varied as desired.

Referring to the drawings, wherein I show one embodiment of my inventionfor the purpose of illustrating the same and wherein the same part isdesignated by the same reference numeral wherever it occurs, Figure 1 isa perspective view of a coin tester adapted to be applied to anysuitable form of coin controlled mechanism, the top of the case beingpartly broken away. Fig. 2 is a longitudinal section of the case showingthe testing mechanism in side elevation. Fig. 3 is an end view showingthe case in section and operating parts in elevation and in their normalposition. Fig. 4 is a view similar to Fig. 3 showing the parts in theposition they occupy at the limit of movement of the mechanism duringthe testing operation. Fig. 5 is a top plan view partly in section ofthe device with the cover removed. Fig. 6 is a central longitudinalsection of the testing disks, the shaft on which they are mounted beingshown in elevation. Fig. 7 is a detail perspective view of a pair ofdisks removed from the shaft. Fig. 8 is a view similar to Fig. 7 showingthe other side of a pair of disks. Fig. 9 is a detail view of the hingedmember of the coin guide. Fig. 10 is a detail perspective view of theshaft on which the disks are mounted and connected thereto, the disksnot being shown on the shaft.

1 designates a rectangular case provided with a cover 2 having slots 3formed therein for the insertion of coins.

4-4 designate a pair of side frames which are secured to a base 5, theseside frames preferably and as shown,

are provided with means by which the case 1 may be secured thereto toinclose the testing mechanism.

6 designates a shaft journaled in hearings in said frames 4 and providedat the end with a handle 7 which is located outside the casing 1.

8 designatea series of disks mounted on the shaft 6, the disks beingsecured to the shaft by any suitable means, as for instance, the pins 9.

10 designate a second series of disks which are loosely mounted on theshaft.

11 are spacing sleeves which, preferably and as shown, are formedintegral with the disks 8 and hold the disks 1O spaced a proper distanceaway from the face of the disks 8. Each of these disks 8 and 10 isprovided with a slot 12, the slot being formed radially of the disk, thewalls of the slot at the bottom 13 and for about half the distance tothe face of each disk being parallel, the walls then being beveledoutwardly as at 14, whereby a slot of a substantially Y-shapedcross-section is formed, as is best seen in Fig. 7 and 8. The disks areassembled on the shaft so that a fast disk and a loose disk alternate.The hub 11 extends from the side of the disk 8 which is provided withthe slot 12. The slot of the loose disk 10 which is separated from thefast disk 8 by spacing sleeve or hub 11, faces the slot in the fast diskwhereby the disks form by their slots a pair of jaws adapted to receivea coin, the length of the hubs 11 determine the size of coin which eachpair of jaws is adapted to receive.

The pair of jaws are preferably and as shown, assembled on the shaft sothat the fast and loose disks of adjacent pairs of jaws are in contactwhereby the loose jaws are held from endwise movement on the shaft. Onthe face of each of the fast jaws opposite that containing the slot, Ipreferably provide a pin 15 adapted to engage a concentric groove 16formed in the adjacent face of the loose disk. i

17 is a stop formed in the groove 16 with which the pin 15 is adapted tocontact, whereby the disk 10 will be caused to rotate with the fast disk8 when the pin and stop are in contact. The pin 15 and the stop 17 inthe slot 16 are so located with respect to each other that when each ofthe fixed jaws is in normal position, the loose jaws will be held intheir normal position by contact between the pin 15 and the stop 17.

18 is a disk mounted on the end of the shaft adjacent the end loose diskand secured to the shaft by a pin 9 the same as the fast disks 8. Thedisk 18 is provided with a pin 15 adapted to engage with the stop 17 inthe groove 16 of the adjacent loose disk, whereby this loose disk willbe caused to turn to its normal position by the pin engaging the stop inthe same manner as the other loose disks.

19 are notches cut in the side of each of the loose I periphery of thedisks when they are in position.

disks with which the free end of springs 20 are adapted to engage. Thesprings 20 are secured at their base to the frame 5 and they are sopositioned that their free ends will engage the notches in the loosedisks to hold the loose disks in their normal position in line with theslots of the fast disks when they are in normal position, as shown inFigs. 5 and 6. These springs also act to produce a sufficient resistanceto the rotation of the loose disks as to cause the pairs of disks tobend a coin held between them which is of less hardness than standard,because the loose disks will not be moved unless the coin or token is ofthe hardness of the standard coin. l

21 is a flanged disk which is secured to one side of the side frames 4and through which the shaft 6 loosely passes. To the inside of theflange of this disk is secured one end of a clock spring 22, the otherend of the clock spring being secured to the shaft 6 whereby the springwill operate to return the parts to their normal position as soon as thehandle is released after the operation of the machine.

In order to prevent slugs formed of iron, such as washers and the like,from being fed into the machine, which might operate the machine, ifthey were of the proper size to accurately fit the slot in a pair ofdisks and of the proper thickness to be positioned in the slots, due tothe fact that they are so hard that they would not be bent under thetwisting action of the pair of jaws, I mount a series of magnets 23 onaplate 24 extendingbetween the side frames 4 and over the disks. Thesemagnets 23 are shown as secured to the plate 24 by means of the screw25, one magnet being arranged over each pair of jaws.

26 is a plate covering all of the magnets except their ends and held inposition by means of the screws 25. The magnets are shown as beinghorse-shoe magnets and the ends of the horse-shoes are so located as tobe adjacent the path of the coin from the coin slots 3 to the slots inthe disks, as is best shown in Fig. 5. From this, it will be seen thatshould an iron washer or similar slug be inserted in the machine, itwill be stopped by the magnets and held, thus, preventing such slug fromentering the machine.

27 designates a frame which extends from one end of the ease to'theother and is located near the top of the case. This frame is providedwith coin slots 28 which register with the slots 3 in the top of thecase.

29 is a guiding flange which extends downward from the top 2 adjacentthe slots 3 on to the top of the frame 27 beside the coin slots 28whereby a coin dropped in the slots 3 is guided from the slots 28.

30 is a plate which forms a pivoted coin guide, it being pivoted at 31to the ends of the frame 27 This plate is adapted to guide the coinafter it passes through the slots 28 down into the slots of the disks.

32 is a spring one end of which is connected to the guide plate 31 andthe other to the side of the casing whereby the plate is held normallyin position to guide the coin in its proper path. The lower end of thisplate extends down close to the periphery of the disks and, preferably,the coin slots in the disks are of such a depth that a portion of thecoins project beyond the It is therefore, necessary to move this plateout of the path of the coins when the disks are rotated to test thesame. it is to permit of this movement that the guide is hinged.

33 designates a rod which is formed ot a main portion of suflicientlength to ex tend from one end of the shat t 6 to nearly the other andis secured to the shaft out side of the side frames 4. The ends 34 oithe rod 33 are bent inwardly at right angles and preferably and asshown, pass through openings in the shaft and are engaged in position bymeans of the nuts 35. The ends 34 of the rod are of such a length thatits main portion 33 will pass over the tops of the magnets and closethereto in order to knock off the magnets any slugs which may be heldthereon, by the magnetic attraction.

3G is a wing cam mounted on the rod 33 at a corner and this wing cam isadapted to engage a projecting end portion 37 of the hinged guide 30.The hinged guide being of sufiicient length to extend outside the sideframe and is provided with slots 38 whereby the guide may straddle saidside frames. From this. it will be seen that the wing cam 36 will movethe guide out of the path of the coin held between the disks in thetesting operation and will also move the guide out from in front of themagnets so that the rod 33 can remove a slug held by the magnets.

39 is a chute extending from the casing l and located in such a positionas to catch any slug knocked off the magnet or a slug which is bent inthe operation of the testing jaws.

' 40 is an arm mounted on the shaft (5 and adapted to contact with thestops ll mounted on the side frame, whereby the revolution of the shafton the operation of the handle in one direction and spring in another,is limited to a hall revolution. The arm on the shaft is so positionedin relation to the stop that when it is against the lower stop in itsnormal position and held there against by the spring, the slots in thedisks will be direct under the coin slots in the cover so any coindropped through the slot in the cover will fall into the correspondingslot in the pair of disks.

In the operation of my device, the parts being in their normal position,a token may be dropped through the proper coin slot 3 and will pass downthrough the corresponding slot 28 and will be guided by the movableguide 30 adjacent to the end of one of the magnets 23. If the token isnot composed of iron. it will pass by the magnet without beingattracted. it. however. it is of iron, it will be caught by the magnetand held with the upper edge of the token extending above the uppersurface of the plate 26. ll", however, the magnets do not stop thetoken. then it drops down into the slots in the disks 8 and 10. Whennow. the handle 7 of the shaft is turned, all of the fast disks 8 turntherewith and if the token is of the proper hardness, it will besul'hcient to cause the loose disk of the pair engaging the token tomove with the fast disk against the tension oi the spring 20 and the twodisks will be revolved together carrying the token between them. Thisrotation will continue until the arm 40 engages the upper pin 41 whenthe parts will be in the position shown in Fig. 4. The striking of thearm 40 against the pin 41 will cause the coin to be released and droppedout of the tester, down into the bottom of the device where it may passon to any suitable coin controlled mechanism. li, however, the token isnot of standard hardof the slots in the disks and the token will fall onto the chute 39 and will be delivered out of the testing machine withoutthe loose disk turning.

The stop 17 in the peripheral slot 16 of the loose disk is so locatedwith respect to the pin 15 on the adjacent fast disk that the fast diskcan turn forward without moving the loose disk. If, however, the loosedisk is moved by a token of proper hardness, then it will be carriedaround and the pin 15 and stop 17 will be in such relation that updn thereturn movement of the shaft, the pin 15 will immediately engage thestop and return the loose disk to its normal position ready to receivethe next token. As soon as it has been returned, the end of the spring20 engaging the notch 19, will hold the same in position to receive thenext token.

While I have described what I believe to be the preferred form of myinvention, I desire to have it understood that many changes may be madein the form, construction and arrangement of parts, and other elementsmay be substituted for those here shown and described, for the purposeof carrying out the function of the elements therein shown anddescribed, without departing from the spirit of my invention, and thatwherein I use the term means, this term is to be understood as coveringall forms of mechanism which are capable of performing the functionascribed to the term in the claims.
